Abstract

<P>PROBLEM TO BE SOLVED: To provide a parameter setting apparatus capable of immediately using a continuously rough setting and a simple setting with a minimum unit respectively when setting a parameter value. <P>SOLUTION: An increase/decrease SW and a slider are provided in each parameter. When continuously and roughly setting a target parameter value, it is executed by using the slider, and when simply setting the target parameter value with a unit of resolution, it is executed by using the increase/decrease SW. Since the slider can set the parameter value corresponding to an operation position, a changed range of the parameter values is decided according to the current parameter value and the maximum value and the minimum value of the parameter values. On the other hand, the increase/decrease SW increases/decreases the parameter value by "1" with a single operation, so that the changed range of the parameter value is "&plusmn;1". <P>COPYRIGHT: (C)2010,JPO&amp;INPIT

Description

  The present invention relates to a parameter setting apparatus for setting parameters, particularly parameter values for controlling multimedia data, and a program for realizing the control method.

  2. Description of the Related Art A parameter setting device that sets parameters, particularly parameter values for controlling multimedia data, has been known.

Such a parameter setting device is provided for each of a plurality of parameters, a first setting operator for changing and setting the value of each parameter by a minimum unit, and a parameter selected from the plurality of parameters. A second setting operator for continuously setting the value of one parameter in accordance with the operation amount, and when the parameter value is to be greatly changed, the second setting operator is used. When it is desired to finely adjust the parameter value in the minimum unit, the first setting operator and the second setting operation are performed according to the setting state of the parameter value, such as using the first setting operator. There is one that can be used properly as a child (see, for example, Non-Patent Document 1). In this conventional parameter setting device, since an expensive dial type operator is used as the second setting operator, only one is provided in order to suppress the manufacturing cost, and any one of a plurality of parameters is selected. By selecting one and assigning it to a dial type operator, the value of one assigned parameter is set by the dial type operator.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of an electronic musical instrument to which a parameter setting device according to an embodiment of the present invention is applied.

A timer 8, a display 9 for displaying various information, for example, a small liquid crystal display (LCD) and a light emitting diode (LED), and the control program Storage device 10 for storing various application programs, various music data, various data, and the like, and a MIDI interface (I / O) for inputting a MIDI (musical instrument digital interface) message or outputting a MIDI message to the outside. F) 11, a communication interface (I / F) 12 for transmitting / receiving data to / from a server computer (hereinafter abbreviated as “server”) 102, and the performance operator 1 via the communication network 101. The tone generator circuit 13 that converts the performance information obtained by reproducing any of the music data stored in the storage device 10 into a tone signal, the tone signal from the tone generator circuit 13, and the like The audio device 103 outputs and mixes with the musical sound signal input via the input signal I / F 16 Or a digital signal processing circuit 14 for imparting various effects to the mixed tone signal or the tone signal itself supplied from the tone generator circuit 13 and converting the tone signal from the digital signal processing circuit 14 into sound. For example, it is constituted by a sound system 15 such as a DAC (digital-to-analog converter), an amplifier, and a speaker.

  The above components 3 to 14 are connected to each other via a bus 18, a timer 8 is connected to the CPU 5, another MIDI device 100 is connected to the MID II / F 11, and a communication network 101 is connected to the communication I / F 12. Are connected to the tone generator circuit 13, and a sound system 15, an input signal I / F 16 and an output signal I / F 17 are connected to the digital signal processing circuit 14. Here, the communication I / F 12 and the communication network 101 are not limited to the wired system but may be a wireless system. In addition, both types may be provided.

  The setting operator 2 has a dial 2a for changing the value of the focus position parameter, and a maximum of 32 (maximum 32) arranged in a matrix of 4 (rows) × 8 (columns) on the small LCD of the display 9. A row selection SW group 2b composed of row selection switches (SW) for selecting each row of parameters and an increase / decrease SW composed of increase / decrease switches (SW) respectively associated with the respective columns of the parameters. The group 2c is composed of a slider group 2d composed of sliders respectively associated with the respective columns of the parameter, and another operation element group 2e.

  The storage device 10 is, for example, a storage medium such as a flexible disk (FD), a hard disk (HD), a CD-ROM, a DVD (digital multipurpose disk), a magneto-optical disk (MO), and a semiconductor memory, and its driving device. The storage medium may be detachable from the drive device, or the storage device 10 itself may be detachable from the electronic musical instrument. Alternatively, neither the storage medium nor the storage device 10 may be detachable. Note that the storage device 10 (the storage medium) can also store the control program executed by the CPU 5 as described above. If the control program is not stored in the ROM 6, the control program is stored in the storage device 10. By reading it into the RAM 7, it is possible to cause the CPU 5 to perform the same operation as when the control program is stored in the ROM 6. In this way, control programs can be easily added and upgraded.

  The MIDII / F11 is not limited to a dedicated one, and may be configured by a general-purpose interface such as RS-232C, USB (Universal Serial Bus), IEEE 1394 (Eye Triple E 1394). In this case, data other than MIDI messages may be transmitted and received simultaneously.

  As described above, the communication I / F 12 is connected to the communication network 101 such as a LAN (local area network), the Internet, or a telephone line, and is connected to the server 102 via the communication network 101. When the above programs and various parameters are not stored in the storage device 10, the communication I / F 12 is used to download programs and parameters from the server 102. The electronic musical instrument serving as a client transmits a command requesting download of a program and parameters to the server 102 via the communication I / F 12 and the communication network 101. Upon receiving this command, the server 102 distributes the requested program or parameter to the electronic musical instrument via the communication network 101, and the electronic musical instrument receives and stores the program or parameter via the communication I / F 12. Downloading is completed by accumulating in the device 10.

  As described above, the digital signal processing circuit 14 mixes the input musical sound signal and gives various effects to the musical sound signal. The target of mixing is a musical sound signal supplied from the sound source circuit 13 and a musical sound signal input from the other acoustic device 103 via the input signal I / F 16. The musical sound signal is composed of a plurality of channels. The channel number and the number of channels of the musical sound signal to be mixed can be freely set. Therefore, the digital signal processing circuit 14 may mix a part of the tone signal from the tone generator circuit 13 and a part of the tone signal from the other acoustic device 103, or both the tone generator circuit 13 and the other acoustic device 103. Even if a musical sound signal is supplied from the above, only a part of the channels of either musical sound signal can be extracted and mixed. Furthermore, various effects can be imparted to the musical tone signal after mixing, or can be imparted to the musical tone signal before mixing. In the latter case, various effects can be given to only some of the channels. The musical tone signal output from the digital signal processing circuit 14 can be supplied not only to the sound system 15 but also to the other audio equipment 104 via the output signal I / F 17.

  As can be seen from the above configuration, the electronic musical instrument of the present embodiment is constructed on an electronic keyboard instrument. However, the electronic musical instrument is not limited to the keyboard musical instrument embodiment, and the string instrument type, the wind instrument type, the percussion instrument type, and the like. Other embodiments may be used. Further, it may be constructed on a general-purpose PC with an externally connected keyboard. Furthermore, it may be constructed on an acoustic device such as a mixer. In that case, a signal processing circuit for mixing a musical sound signal, an AD / DA conversion circuit, and the like are essential components, but a tone generator circuit is not an essential component. In addition, the functional configuration generated by generating a musical sound signal, specifically, the constituent elements 13 to 17 and the other functional configuration for setting parameters are integrally formed in the present embodiment. Alternatively, it may be formed separately.

  The electronic musical instrument according to the present embodiment has a function of setting parameters, particularly parameter values for controlling multimedia data, as a main function. Examples of parameters for controlling multimedia data are stored in various registers provided in the tone generator circuit 13 and provided in the digital signal processing circuit 14 and various tone generation parameters used by the tone generator circuit 13 for tone generation. The effect imparting parameters, the mixing parameters, and the automatic performance that are used when applying various effects to the musical tone signal stored in the various registers and supplied by the digital signal processing circuit 14 or when mixing the supplied musical tone signal. A MIDI sequencer (for example, stored in the storage device 10 in advance, downloaded from the server 102 via the communication I / F 12 and the communication network 101, and stored in the storage device 10). The parameters required to perform the action (i.e. Rather than parameters necessary for sound generated directly, the parameters required to generate the performance information), instead of the tone, and the like parameters for controlling the video.

  Further, the parameters to be set by the electronic musical instrument of the present embodiment are supplied from the outside via the MIDII / F11 or the communication I / F12 even if stored in advance in the ROM 6 or the storage device 10, and the RAM 7 or It may be stored in the storage device 10 or the like.

  FIG. 2 is a plan view of a part of the panel surface around the small LCD 9a constituting the display 9. As shown in FIG.

  As shown in the figure, around the small LCD 9a, a dial 2a, a row selection SW group 2b, an increase / decrease SW group 2c, a slider group 2d, and category selection SWs 2e1 and 2e2 are arranged.

  The electronic musical instrument of the illustrated example shows a state in which the “TUNE” category is selected from the plurality of parameter categories after the parameter setting mode is selected and the operation mode shifts to the parameter setting mode. At this time, on the small LCD 9a, the parameters belonging to the category of “TUNE” (19 parameters in the illustrated example) and their current setting status are the parameter names and numerical values indicating the parameter setting values themselves ( "50") and a knob-shaped indicator that visually indicates the current set value for the settable range of the parameter. The name of the selected category (that is, “TUNE”) is hatched so that it can be seen that the category is being selected. Of course, the “slashed line” has been adopted so that it can be easily drawn in the drawing, and any form such as reverse display, change of display color and display font may be adopted. The same applies to the other “hatched lines”.

  The dial 2a can change the value of one parameter at the focus position among a plurality of parameters arranged in a matrix. When the dial 2a is turned in the direction in which the clock hand advances, the value of the parameter is increased by a value corresponding to the rotation amount, while when the dial 2a is turned in the reverse direction, the value of the parameter is increased by a value corresponding to the rotation amount. Decrease. The focus position is indicated by a parameter f and a square f surrounding the knob-shaped indicator. In the present embodiment, the movement of the focus position f in the column direction is associated with the increase / decrease SW in response to the operation of any increase / decrease SW included in the increase / decrease SW group 2c. This is done together with the increase / decrease of the parameter value.

  Each row selection SW constituting the row selection SW group 2b is arranged in association with each row of the parameters arranged in the matrix, and when the user presses one row selection SW, the row selection SW is associated with the row selection SW. A row is selected. Of the four row selection SWs arranged on the left side of the small LCD 9a and the four row selection SWs arranged on the right side, those having the same horizontal position, for example, a row selection SW displayed as “B” and “F” The row selection SW displayed as "" selects the second row no matter which button is pressed. However, the settable parameters are not necessarily arranged in all columns of all selectable rows. In the illustrated example, only one row of settable parameters is arranged in the first column to the third column, and no settable parameter is arranged in the fourth column. FIG. 2 shows a state when the row selection SW labeled “F” (or “B”) is pressed in such a parameter arrangement state. That is, when the line selection SW displayed as “F” is pressed, it indicates that the user wants to select the second line. When a row parameter (in the example shown, “PITCH BEND RANGE” parameter) is selected, and no configurable parameter is placed in that row, the parameter (Fig. In the example shown, the parameter “TRANSPOSE” is selected. Furthermore, when there is a column (in the illustrated example, the fourth column) in which no parameter is arranged, the row of that column is naturally not selected.

  As can be seen from the example of FIG. 2, even if the expression “arrange parameters in a matrix” is used, the matrix in which the parameters are actually arranged has omissions (locations where no parameters are arranged). This “matrix” does not match the mathematically defined “matrix”. However, when there are no omissions and all 32 parameters are arranged, or there are omissions in units of rows or omissions in columns (see FIG. 4), the arrangement shape of the parameters is mathematically defined. The shape of the “matrix” may coincide with the shape of the “matrix”, which may not completely match the mathematically defined shape of the “matrix”. In the abstract, it is expressed as “parameters are arranged in a matrix”.

  FIG. 4 is a plan view of a part of the panel surface around the small LCD 9a when the parameter “TRANSPOSE” is deleted from FIG. In FIG. 4, since no parameters are arranged in all the rows of the first column to the fourth column, no row can be selected for the first column to the fourth column.

  Returning to FIG. 2, each increase / decrease SW constituting the increase / decrease SW group 2c is associated with each column of the parameters arranged in the matrix, and when any increase / decrease SW is pressed. The value of the parameter at the position specified by the row selected by the row selection SW and the column associated with the increase / decrease SW is increased or decreased by “1” in response to a single press. At this time, when an increase / decrease SW associated with a parameter (in a row) different from the parameter of the focus position f is pressed, the focus position f is also associated with (and selected from) the increase / decrease SW. Move to the parameter position. In this case, only the focus position f may be moved by the first press of the increase / decrease SW, and the value of the parameter may be changed by the second and subsequent presses.

  Similarly to each increase / decrease SW, each slider constituting the slider group 2d is also associated with each column of parameters arranged in the matrix, and when any slider is operated, the row selection SW The value of the parameter at the position specified by the row selected by and the column associated with the slider is changed. However, unlike each increase / decrease SW, the parameter value is not changed by “1”, but is changed to a value corresponding to the operation position, and the focus position f does not move no matter which slider is operated.

  FIG. 3 is a diagram showing an example of a data structure for setting parameter values arranged in the matrix.

  As shown in the figure, in a partial area of the RAM 7, a pointer storage area for storing a pointer indicating the position of a register in which each value of the parameters arranged in the matrix is actually set, and A focus position storage area for storing the focus position in the pointer storage area is secured.

  The pointer storage area is formed in a matrix of 4 (rows) × 8 (columns), and each row has an integer value from “0” to “3”, and each column has an integer value from “0” to “7”. (It is customary to start with “1” when counting each row and each column and start with “0” when assigning an integer value to each row and each column. Yes, the latter is because it is easier for the CPU 5 to handle, but there is no further reason, so one may be matched to the other). Therefore, each pointer stored in the pointer storage area is designated by (row number, column number), like each element of the mathematical matrix.

  In the present embodiment, only one pointer storage area is provided, and each time a category is changed, a pointer indicating each parameter belonging to the category is stored in the pointer storage area. Note that the register in which the parameter value is actually set is fixed for each parameter and does not fluctuate. Therefore, if the parameter is determined, the pointer is also uniquely determined. Therefore, table data in which each settable parameter and its pointer are associated with each other is created in advance and stored in, for example, the ROM 6, a category is selected, and the parameters belonging to the category are displayed on the small LCD 9a. When displaying, a pointer corresponding to each parameter is read from the table data and stored in a corresponding position in the pointer storage area. In addition, there is a partial area in which pointers are not stored in the pointer storage area, and information indicating “not assigned” (for example, “FF”) is stored in the partial area. However, information indicating “not assigned” is stored only in a column in which no parameter is arranged in any row, and is not stored in a column in which a parameter is stored in some rows. More specifically, as shown in FIG. 2, the parameters are arranged only in the fourth row from the first column to the third column (the parameter is the one with the larger row number (in this embodiment, 4), the first column (“0”) to the third column (“2”) are shown in the pointer storage area of FIG. Are stored in the first row (“0”) to the third row (“2”) as well as the fourth row (“3”). In this way, in the pointer storage area, the same pointer as the pointer stored in the partial area nearby is also stored in the partial area where the pointer is not actually stored. I want to make it easier.

  FIG. 5 is a diagram showing an example of a data structure for setting parameter values displayed on the small LCD 9a of FIG. On the small LCD 9a of FIG. 4, since no parameters are arranged in all the rows corresponding to the columns from the first column to the fourth column, the first column (“0”) to the fourth column ( Information indicating “not assigned” is stored in all rows (“0” to “3”) for the columns up to “3”).

  Returning to FIG. 3, the focus position storage area stores information indicating the current focus position, (in this embodiment, (row number, column number)). In the illustrated example, (1, 0) is stored in the focus position storage area. That is, the current focus position is a parameter in the second row and first column (a parameter indicated by a “pointer to the MASTER TRANSPOSE register” surrounded by a thick line in the pointer storage area). 2 is in the fourth row and first column, whereas the focus position stored in the focus position storage area in FIG. 3 is in the second row and first column. Have different line numbers. This is because, even if no parameter is actually arranged in the row selected by the user using the row selection SW, when the parameter is arranged in the row closest to the row, the parameter is also displayed in the row. The pointer of the parameter is stored at the corresponding position in the pointer storage area, and the line at the focus position is selected as the selected line regardless of whether the parameter is placed in that line. This is because it is desired to simplify the control of the focus position (particularly, the line) even if a flaw occurs between the line at the focus position and the line on the display. Therefore, if it is not necessary to simplify the control of the focus position, the line at the focus position and the line on the display may be matched. In this case, the configuration of the parameters arranged in a matrix and the configuration of the pointer stored in the pointer storage area may be matched. That is, in this case, in the example of the pointer storage area of FIG. 3, in the area surrounded by the broken line, the partial area surrounded by the rows “0” to “2” and the columns “0” to “2” , Information indicating “not assigned” is stored.

  The control process executed by the electronic musical instrument configured as described above will be described first with reference to FIGS. 2 and 6 and then in detail with reference to FIGS.

  For example, after the user operates a mode switch (not shown) included in the other operator group 2e and the operation mode shifts to the parameter setting mode, the user operates the category selection SW 2e1 and 2e2 to execute “TUNE”. When the second row is selected by operating the row selection SW labeled "F" and selecting the second row, the "9" is displayed on the small LCD 9a of the display 9 as shown in FIG. The parameters belonging to the category are displayed in a matrix, and the current setting status of all parameters is displayed with the parameters in the second row selected. However, since no parameter is arranged in the second row for the columns from the first column to the third column, the arranged row, that is, the fourth row is apparently selected. When the user rotates the dial 2a in this display state, the value of the parameter of the focus position f (in the illustrated example, “MASTER TRANSPOSE”) is increased or decreased by a value corresponding to the rotation direction and the rotation amount.

  On the other hand, when the user presses the third row increase SW included in the increase / decrease SW group 2c once in the parameter setting state, the focus position f moves to the third column, and the parameter ( In the illustrated example, the value of “KBD TRANSPOSE”) increases by “1”.

  Furthermore, when the user operates the slider in the fifth column included in the slider group 2d in the parameter setting state before the increase SW in the third column is pressed, the parameter in the second row and the fifth column (in the illustrated example). , “LEFT PITCH BEND RANGE”) value is set according to the operation position. At this time, since the focus position f does not change, when the user subsequently rotates the dial 2a, the parameter of the focus position f, that is, the value of “MASTER TRANSPOSE” is increased or decreased by a value corresponding to the rotation direction and the rotation amount. The

  As described above, in the present embodiment, by operating each increase / decrease SW included in the increase / decrease SW group 2c, the focus position is moved to set the value of each parameter, or vice versa. In addition, by operating each slider included in the slider group 2d, it is possible to set the value of each parameter without moving the focus position, so that the user can perform the focus position switching control as desired. While doing, it is possible to set the value of each parameter.

  In the present embodiment, an operation for setting the value of each parameter without moving the focus position while using the increase / decrease SW as an operator for setting the value of each parameter by moving the focus position. Although a slider is used as a child, the types and combinations of the operators are not limited to this, and both the former and the latter are of the same type (for example, increase / decrease SW, slider, knob, Any type of wheel or numeric keypad that can change the parameter value may be used, and when the types of the former and the latter are different, the above example is used. Two types of operators arbitrarily selected from a plurality of operators may be used.

  When the value of a parameter to be set is set by operating a slider included in the slider group 2d, the value of the parameter is set to a value corresponding to the operation position of the slider as described above. FIG. 6 is a graph showing an example of a conversion table for converting the operation position of the slider into a parameter setting value. The figure illustrates one type of linear conversion table (drawn with a broken line) TBL1 and three types of nonlinear conversion tables (drawn with a solid line, a one-dot chain line, and a two-dot chain line) TBL2 to TBL4. . In the present embodiment, a conversion table is set for each parameter, and when the slider is operated, the operation position is converted into a parameter value by the conversion table set for the setting target parameter. The obtained parameter value is set as the parameter to be set. Note that the conversion table stored in advance in the ROM 6 may be read and used.

  For example, when the linear conversion table TBL1 is set as a parameter to be set, the operation position of the slider is converted into a parameter value proportional to the position, so if it does not matter whether the focus position moves, at first glance, It is felt that there is not much difference from the parameter value setting operation by increasing / decreasing SW. However, in both cases, the change range of the parameter value that can be changed and set in one operation is different first, and second, the difficulty of the operation for setting increase / decrease of the resolution unit (minimum unit) to the parameter value is different. ing. In other words, since the slider can set the parameter value according to the operation position, the change range of the parameter value is determined by the current parameter value and the maximum value and the minimum value of the parameter value. Any integer value from the minimum value “0” to the maximum value “127” can be set, and if the current parameter value is “50”, the change range of the parameter value is maximum “77” in the plus direction. The increase / decrease SW increases / decreases the parameter value by “1” in one operation, so the change range of the parameter value is “± 1”. It is. On the other hand, since the slider provided on a narrow operation panel such as a musical instrument has a narrow operation range, the resolution is 7 bits (128 divisions), and even if the slider can be operated in units of resolution due to the structure of the slider. However, skill is required to operate in units of resolution, whereas increase / decrease SW can be increased or decreased by the amount of resolution very easily by one operation. Therefore, while the slider can set the parameter value to be set continuously roughly, the increase / decrease SW can easily set the parameter value to be set in units of resolution.

  As described above, in the present embodiment, when setting the same parameter value, the user can immediately use the rough setting and the simple minimum unit setting immediately.

  In addition, when the nonlinear conversion tables TBL2 to TBL4 are used as the conversion table, in addition to the above effects, a low resolution part and a high resolution part can be mixed within the operation range of the slider. Accordingly, by using different nonlinear conversion tables having different shapes, the target parameter value can be reached quickly.

  Next, this control process will be described in detail.

  FIG. 7 is a flowchart showing the procedure of the main routine executed by the electronic musical instrument of the present embodiment, particularly the CPU 5.

In this main routine, the CPU 5 mainly
(1) Initial setting process (step S1)
(2) Setting target parameter switching process (step S2)
(3) Increase / decrease SW operation processing (step S3)
(4) Slider operation processing (step S4)
(5) Dial operation processing (step S5)
(6) Row selection SW operation processing (step S6)
(7) Music signal generation processing (step S7)
Each process is performed. This main routine is started when the power is turned on by a power switch (not shown) included in the other operator group 2e. After startup, the initial setting process (1) is executed once, and subsequently, the processes (2) to (7) are sequentially executed. When the process (7) is completed, the process returns to the process (2), and the processes (2) to (7) are repeatedly executed until the power is turned off by the power switch.

  In the initial setting process (1), the CPU 5 clears the RAM 7, sets the values of various parameters to default values, starts the timer 8 timing, and sets the operation mode to the default mode. Make initial settings.

  When the user selects the parameter setting mode by operating the mode switch, the CPU 5 shifts the operation mode to the parameter setting mode, and then proceeds to the setting target parameter switching process (2). In the setting target parameter switching process (2), the CPU 5 switches the setting target parameter for each page in accordance with the operation of the category selection SW 2e1 and 2e2 by the user, and reflects it on the display on the small LCD 9a. Here, “page” refers to one screen of the small LCD 9a. In other words, in the present embodiment, a maximum of one page parameter (in this embodiment, a maximum of 32 included in a 4 × 8 matrix) can be set for each selectable category, and the category is switched. Each time, the parameter to be set is switched to the parameter belonging to the category after switching, and at the same time, the parameter for one screen of the small LCD 9a is switched to the parameter belonging to the category after switching.

  FIG. 8 is a flowchart showing a detailed procedure of the increase / decrease SW operation process (3).

  In this (3) increase / decrease SW operation processing, first, the CPU 5 always checks whether any increase / decrease SW included in the increase / decrease SW group 2c has been operated (step S11). When the decrease SW is not operated, the (3) increase / decrease SW operation processing is ended (step S11 → return). On the other hand, when any increase / decrease SW is operated, the focus position storage area is moved. The focus position stored in is read out, and the row number of the read focus position is acquired (step S12). In the example of FIG. 3, since (1, 0) is stored as the focus position in the focus position storage area, “1” is acquired as the row number in the process of step S12.

  Next, the CPU 5 acquires the column number of the operated increase / decrease SW (step S13). Since the increase / decrease SW is associated with the column of the matrix, when the operated increase / decrease SW is specified, the row number associated with the increase / decrease SW is easily obtained. In the example of FIG. 2, for example, when the increase SW in the sixth column is operated, “5” is acquired as the column number in the process of step S13.

  Next, the CPU 5 increments (or decrements) the value of the parameter designated by the acquired row number and column number by “1” (step S14). Here, “increment” is made when the increase SW is operated, and “decrement” is made when the decrease SW is operated. As described above, when “1” is acquired as the row number and “5” is acquired as the column number, the pointer at the position (1, 5) in the pointer storage area of FIG. Since “PITCH BEND RANGE register” is shown, the increment target parameter is “RIGHT1 PITCH BEND RANGE”, and the value (that is, the value stored in the register) is incremented by “1”. Note that since all the parameters to be set can only take values within a predetermined range, the increase SW is operated in a state where the maximum value is set, or the decrease SW is set in a state where the minimum value is set. When is operated, any operation becomes invalid.

  Next, the CPU 5 changes the column number in the focus position to the column number acquired in step S13, and updates the focus position in the focus position storage area with the focus position whose column number has been changed (step S15). ). Although the column number acquired in step S13 may be the same as the column number of the focus position, in this case, the update process in step S15 is not necessary. Of course, even in this case, no problem occurs even if the update process of step S15 is performed.

  Then, the CPU 5 updates the display of the small LCD 9a (Step S16). As a result, in the example of FIG. 2, the focus position f moves to the parameters in the second row and sixth column (see FIG. 4; however, since the number of parameters that can be set differs between FIG. 4 and FIG. 2). 4 does not show a state in which the focus position f shown in FIG. 2 is simply moved), and its parameter value is changed from “50” to “51”, and a knob-shaped indicator The designated position is also changed.

  FIG. 9 is a flowchart showing a detailed procedure of the slider operation process (4).

  In this (4) slider operation processing, first, the CPU 5 always checks whether any slider included in the slider group 2d has been operated (step S21), and if any slider has not been operated, this (4 ) End the slider operation process (step S21 → return). If any slider is operated, the process proceeds to step S22.

  The processes in steps S22 and S23 are substantially the same as the processes in steps S12 and S13 except that the type of the operated operator is different from the processes in steps S12 and S13. Since the analogy can be made immediately, the explanation is omitted.

  Next, the CPU 5 acquires the operation position of the slider (step S24). When the slider has a predetermined operation range, the operation range is divided with a predetermined resolution, and the user determines the operation position by operating, for example, an operation knob (not shown), the CPU 5 A numerical value (integer value) corresponding to can be acquired from the detection circuit 4. Therefore, strictly speaking, in step S24, a numerical value corresponding to the operation position is acquired, but since the operation position and the numerical value are associated one-to-one, the operation position is acquired for convenience of explanation. .

  Next, the CPU 5 acquires a parameter value from the operation position acquired in step S24 using the conversion table (step S25). In this embodiment, once the parameters are determined, the conversion table to be used is also uniquely determined (the user himself / herself selects in advance or the optimum one is selected at the factory setting). Therefore, CPU5 acquires a parameter value from the acquired operation position using the conversion table.

  Next, the CPU 5 changes the value of the parameter specified by the acquired row number and column number with the parameter value acquired in step S25 (step S26). If the specific example used in the description of the processing of step S14, that is, the example in which “1” is acquired as the row number and “5” is acquired as the column number is used in the same manner, the parameter to be set is “RIGHT1”. PITCH BEND RANGE ", and the value (that is, the value stored in the register) is changed to the value acquired in step S25. In the present embodiment, any slider included in the slider group 2d is a motor slider (the operation knob is automatically moved to the operation position corresponding to the set value according to the set value of the corresponding parameter). In the processing of step S26, the current value of the parameter to be set and the parameter value acquired according to the operation position of the slider may be opened. The value of the target parameter is immediately changed to the acquired parameter value. For example, when any trouble occurs due to a sudden change in the parameter value, the parameter setting that causes a sudden change in the parameter value may be gradually changed to the target value. Alternatively, the parameter value may not be changed immediately after the slider is operated, but may be changed to a parameter value corresponding to the operation position after a predetermined time has elapsed. Further, when the operation position of the slider passes the operation position corresponding to the current value of the parameter, the operation of the slider may be validated and the parameter value may be changed.

  Next, the CPU 5 updates the display of the small LCD 9a in the same manner as the process of step S16 (step S27). Accordingly, in the example of FIG. 2, the parameter value in the second row and sixth column is changed from “50” to a value corresponding to the operation position of the slider while the focus position f remains unchanged, and the indication of the knob-shaped indicator The position is also changed.

  FIG. 10 is a flowchart showing a detailed procedure of the dial operation process (5).

  In this (5) dial operation process, first, the CPU 5 always checks whether or not the dial 2a has been operated (step S31). If the dial 2a has not been operated, this (5) dial operation process is terminated (step S31). On the other hand, when the dial 2a is operated, the focus position stored in the focus position storage area is read out and acquired (step S32).

  Next, the CPU 5 acquires the operation amount of the dial 2a (step S33). From the dial 2a, for example, a numerical value corresponding to the operation position when one round is divided with a predetermined resolution is supplied via the detection circuit 4, so the CPU 5 calculates a numerical value corresponding to the operation position in a predetermined cycle. By monitoring, the operation amount of the dial 2a can be acquired. Note that the operation amount can be either a positive number or a negative number, and takes “positive” when the dial 2a is rotated in the same direction as the direction in which the hands of the watch advance, and “negative” when the dial 2a is rotated in the opposite direction. You should take it.

  Next, the CPU 5 uses the conversion table to acquire the change amount of the parameter value from the operation amount acquired in step S33 (step S34). Here, the conversion table is different from the conversion table used in step S25. The setting of the parameter value using the dial 2a is a well-known technique, and the feature of the present invention is not in the method of setting the parameter value using the dial 2a. Further explanation is omitted.

  Next, the CPU 5 increases the value of the parameter designated by the focus position by the amount of change acquired in step S34 (step S35). Here, since the change amount has a positive / negative sign, an increase in the negative number naturally decreases by an absolute value of the change amount. As mentioned in the description of the processing in step S14, any parameter to be set can only take a value within a predetermined range. Therefore, when the amount of change is added, the maximum value of the parameter is exceeded. Or conversely, the minimum value of the parameter is exceeded. In this case, the parameter value is set so as not to exceed the maximum value and the minimum value.

  Next, the CPU 5 updates the display of the small LCD 9a in the same manner as the process of step S16 (step S36). Thereby, in the example of FIG. 2, the parameter value of the focus position f is changed from “50” to a value corresponding to the operation amount of the dial 2a, and the indicated position of the knob-shaped indicator is also changed.

  FIG. 11 is a flowchart showing a detailed procedure of the row selection SW operation process (6).

  In this (6) row selection SW operation process, first, the CPU 5 always checks whether any row selection SW included in the row selection SW group 2b has been operated (step S41), and operates any row selection SW. If not, the (6) row selection SW operation processing is terminated (step S41 → return). On the other hand, when any row selection SW is operated, the focus stored in the focus position storage area is stored there. The position is read, and the line number in the read focus position is updated with the line number selected by the operated line selection SW (step S42). In the example of FIG. 4, for example, when the row selection SW labeled “G” is pressed, the third row is selected, and the parameter of that row, that is, the parameter “OCTAVE” is selected. The focus position f is also moved from the second row and sixth column ("RIGHT1 PITCH BEND RANGE" parameter) to the third row and sixth column ("RIGHT1 OCTAVE" parameter).

  Next, the CPU 5 updates the display on the small LCD 9a (step S43).

  Returning to FIG. 7, in the musical tone signal generation process of (7), the CPU 5 receives performance information from the detection circuit 3 according to a performance performed by the user using the performance operator 1, or the user performs When the MIDI sequencer is started, music data to be automatically played is selected, and the performance information is supplied from the MIDI sequencer by instructing the start of the automatic performance, the performance information is supplied to the tone generator circuit 13. Then, the generation of the musical tone signal is instructed. As a result, the tone generator circuit 13 generates a tone signal corresponding to the supplied performance information and supplies it to the subsequent digital signal processing circuit 14.

  In this embodiment, a row of parameters arranged in a matrix is selected by the row selection SW, and any one of the operators (increase / decrease SW or slider) associated with each column of the parameter is selected. By operating, the value of the parameter specified by the column associated with the operated operator and the selected row is set according to the operation. Is reversed, the column of the parameter is selected by the column selection SW, and one of the operators associated with each row of the parameter is operated, so that it is associated with the operated operator. The value of the parameter specified by the row and the selected column may be set according to the operation.

  In this embodiment, the parameters are arranged (displayed) in a matrix on the small LCD 9a. However, the present invention is not limited to this, and the parameters are printed in a matrix on the panel surface and selected around the parameters. LEDs indicating rows and columns may be arranged, or instead of LEDs indicating rows and columns, row numbers and column numbers may be displayed by, for example, 7 segment LEDs, or LEDs may be arranged in a matrix. .

  Furthermore, in the present embodiment, the parameters are arranged in a matrix, but the present invention is not limited to this, and a plurality of parameters may be arranged in one row or one column. When a plurality of parameters are arranged in one row, the row selection SW is not necessary. On the other hand, when a plurality of parameters are arranged in one column, operators (for example, increase / decrease SW and slider) for setting parameter values are provided in association with each row instead of the row selection SW.

  In the present embodiment, the types of parameters set by each slider included in the slider group 2d are not particularly mentioned, and basically any type of parameters may be used. By assigning mutually related parameters to at least some of the plurality of sliders included in the slider group 2d and setting the values of the parameters assigned by these some sliders, the operation of the slider Since the rough shape of the set parameter value can be visually grasped according to the position, it is possible to assist the user in setting the parameter value. For example, when a partial envelope obtained by dividing the entire envelope of a certain channel into a plurality of parameters is used as an interrelated parameter, the operation position after setting the partial slider is roughly the envelope. When the rough setting is not satisfied, the user can perform fine adjustment using the increase / decrease SW provided corresponding to each of the partial sliders. As another example of the parameters related to each other, the volume for each channel can be given.

  Furthermore, in this embodiment, each parameter value is set via a pointer indicating the register position where the parameter value is actually set. However, the present invention is not limited to this, and the parameter value is directly set. The corresponding register may be set. In this case, instead of indicating the position of the corresponding pointer in the pointer storage area, the focus position may directly indicate the register of the corresponding parameter such as a parameter name.
